The dimensions of the dowel pin comply with DIN 6325. Advantages: Ideal for fixture construction Dimensionally stable even at high temperatures Electrically insulating

Parallel keys are used for the implementation of shaft-hub connections. These are positive connections which are used to transmit torque.

Form A locating pins are used to position workpieces and fixture parts in reamed holes. The flattened Form C can be used to bridge tolerances in hole spacing or to secure the part to be positioned in one direction only. The Form A locating pins can also be used as limit stops or fixture feet. Advantages: Cerazur is extremely impact and bend resistant. The basis of this material is zirconium oxide. It is a composite metal-ceramic material. Drawing reference: Form A and B: cylindrical locating pin Form C and D: flattened locating pin

Ceramic bearings Si3N4. Bearing cage PTFE. For most applications Si3N4 is the preferred material for ceramic bearings. Silicon nitride bearings are light, very hard and highly wear resistant. High and ultrahigh performance bearings are used in e.g. aerospace technology, metal production industries (high application temperatures), machine manufacturing, chemical industries (chemically aggresive substances), pharmaceutical and medical industries, semiconductor and biotechnology (clean room enviroments which may not be contaminated by lubricants). On request Special version with PEEK ball cage. Without ball cage.
